Capture/Replay: Support glCopyImageSubData with compressed formats Special Forces Group 2 uses glCopyImageSubData() to copy compressed texture data, which requires special handling for ANGLE's frame capture since compressed texture data can't be read back. To support this, when glCopyImageSubData() is called with textures using compressed formats, a new mCachedTextureLevelData entry will be created for the destination texture which is a copy of the source texture data. Note that this implementation only supports copying the full level data. http://anglebug.com/5604 will track adding support for partial level copies if an app requires that in the future.
